| WQStat Plus Version 9.4 Has Been Released!|
WQStat Plus™ has been
developed with assistance from Colorado State University faculty,
the original developers of WQStat II. A subset of the state-of-the-art Sanitas package, WQStat Plus™ is designed to provide statistical solutions for various types of environmental
media (e.g. surface water, groundwater, etc.). This powerful reporting
and analysis tool is provided in a Windows-based environment.
WQStat™ is designed for the more experienced user who is familiar with the underlying assumptions of statistical methods, and it provides distributional pre-tests but does not automate them. It is also an ideal statistical software program for projects requiring a small volume of statistical analyses.
For instance, in deciding whether to construct a nonparametric or a parametric test, WQStat™ (unlike our Sanitas™ package) requires the user to manually test each data set for normality, and construct a statistical test based on those results. Plots are generated in single-plot format, and printed in the same manner. Sanitas's Summary Tables and Batch report features are not available in WQStat Plus™.
The other key difference between the two programs is their software licensing. Sanitas™ is licensed on a per-facility basis requiring a site license for each facility (and no restrictions on the number of users). WQStat Plus™ is licensed per-user, allowing one installation per software purchase.
